1、Designation: E1273 88 (Reapproved 2013)Standard Specification forColor Coding of Reusable Laboratory Pipets1This standard is issued under the fixed designation E1273; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last
2、 revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers a system of color coding forone-mark pipets for identification of nominal capacities, andfor gra
3、duated pipets for identification of nominal capacities andunits of sub-division.1.2 This specification applies to one-mark and graduatedpipets of the nominal capacities listed in Table 1 and Table 2,respectively.NOTE 1Many pipets not covered by other ASTM standards areincluded in Table 1 and Table 2
4、 in order, firstly, to ensure uniformity ofcolor coding as far as possible for non-standard as well as standard pipetsand, secondly, to reserve suitable codes for possible future standards forother types of pipet.1.3 The values stated in SI units are to be regarded asstandard. No other units of mea
5、surement are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory li

Significance and Use3.1 The purpose of this specification is to ensure that if acolor code is used on pipets, all manufacturers will use thesame code; it i
7、s not intended as an encouragement of colorcoding if this is not required.4. Color Properties4.1 CodingThe color coding used on one-mark pipetsshall be in accordance with Table 1, and graduated pipets shallbe in accordance with Table 2.4.2 VariationsVariations in the enamels used in the meth-ods of
8、application appropriate for pipets made from differenttypes of glass inevitably result in minor variations of color, andit is therefore not appropriate to specify closely the sevencolors listed in the tables.5. Marking Requirements5.1 The color code shall take the form of color bandsextending at lea
9、st 150 around the circumference of the pipetand situated not more than 70 mm from the top of the pipet andnot less than 20 mm above the nearest graduation line.5.2 For a code consisting of a single band of color, the bandshall be 5 to 10 mm wide. For a code consisting of two bandsof color, each band
10、 shall be 3 to 5 mm wide and the two bandsshall be separated by a space of 2 to 3 mm. Color bands do nothave to be continuous but may be broken as long as they cover40 % of the circumference of the pipet.NOTE 2Pipets calibrated to deliver by blowing out the last drop shallbe identified by a wide ban
11、d or two narrow bands permanently marked ontheir top end.6. Sampling and Testing6.1 Sampling and testing shall be in accordance with Speci-fication E1157.7.
